Abstract
Low crop productivity is a general problem facing most farming systems in sub-Saharan Africa
(SSA). These low yields are pronounced in grain legumes and are often associated with declining
soil fertility and reduced N2-fixation due to biological and environmental factors. Biological
nitrogen fixation (BNF), a key source of N for farmers using little fertilizer, constitutes one of
the potential solutions and plays a key role in sustainable grain legumes production. Phosphorus
is needed in relatively large amounts by legumes for growth and has been reported to promote
legumes growth and yield, nodule number and nodule mass in different legumes. Potassium
influences the water economy and crop growth through its effects on water uptake, root growth,
maintenance of turgor, transpiration and stomatal regulation. Various Studies have shown that
Rhizobium inoculation, phosphorus and potassium has the potential to improve legumes growth,
seed yield, nitrogen fixation and also nutrient up take of legumes. The potential role of rhizobia
inoculants and supplementation of P an K with respect to growth, nitrogen fixation, nutrient
uptake, total leaf chlorophyll content, and grain yield of legumes are given attention in this
review.
